摘要
Results are reported obtained in a study aimed to develop a technology for quantitative transfer of lithium from an aqueous solution to soluble (chloride, nitrate, or sulfate) and insoluble (carbonate) salts via, respectively, evaporation and precipitation. The thus synthesized samples are identified and their phase composition is determined by X-ray phase analysis. The samples were examined as regards their stability in storage in air. It was shown that lithium sulfate and carbonate are the most stable forms among the compounds considered.
